[Numpy-discussion] numarray patch: use Apple's vecLib on Mac OS X

Hi,
I've noticed your patch for MacOS X, and I think that a better solution  
should use sys.platform instead of a path search, since Apple could  
always change its framework location. I've also removed the  
VECLIB_PATH/Headers from the include path because AFAIK Apple gcc  
already knows where to search for the vecLib framework. Here it is a  
diff output between my addons.py and the CVS one.

HTH,
   Andrea.
